x-2=sqrt(7x+4)

Solution

x - 2 = 7 x + 4

Solution

x = 11

Solution steps

x - 2 = 7 x + 4

Square both sides:

x^{2} - 4 x + 4 = 7 x + 4

x^{2} - 4 x + 4 = 7 x + 4

Solve

x^{2} - 4 x + 4 = 7 x + 4 : x = 11, x = 0

x = 11, x = 0

Verify Solutions:

x = 11

True

, x = 0

False

The solution is

x = 11

sqrt(8x+8)-20=-12

8 x + 8 - 20 = - 12

sqrt(x)-sqrt(x-15)=3

x - x - 15 = 3

a=sqrt(a)sqrt(a)

a = a a

x + x^{0.1} = 100

x - 4 = 2
